Positive developer - 50 grams

This product is used as the developer on our positive photo-resist printed circuit boards. Includes instructions.

Mix the developer in 1 liter of 77°F water. Gently agitate an exposed PCB in solution. Exposed areas of resist will dissolve into the solution, leaving the green resist in areas that were not exposed to UV light.

If the resist is not fully removed from the exposed areas of the PCB, the UV exposure received may have been insufficient. Possible causes are: Insufficient exposure time, the UV source is old and not producing enough UV light, incorrect UV light frequency (350~450µm UV light source recomemded) or the artwork is not UV light transmissive.
